Excellent, maybe we could convince the right people to put it on Freedesktop.org or something and generic'ify the code so it could get adopted by as many projects as possible in the longrun. Regardless it is a great idea, I hate getting a crash and noticing that I forgot to install the symbols. > Unfortunately it depends on some Ubuntu-specific kernel patches to work > right.

(That's why upstream rejected this patch.) Well, it has to be in Ubuntu' own best interest to help with this, the more work is upstream the better for all of us.

This would only be true for the C style apps right, we'd need additional work at the time where Apport gets support for Python (yuck!) and Mono (yay!) or have I been dipping in Ingo cloning fluid again? > Anyway, if anyone's interested in checking it out, you can get a copy of > my apport SRPM here: > > http://homepage.mac.com/wgwoods/fedora/apport/apport-0.75-0.rc2.fc7.src.rpm > > I *really* want to get this working for F8. That would make a great addition to our line up, though by no means a perfect solution to all our problems. It only does crashes and right now the worst problem I'm seeing on Development is occasional rampant memory abuse leading to total system failure - tracking down that kind of problem really could benefit from a similar little helper tool. - David
